I keep a 3-ring binder. YEAY for plastic sheet protectors - use them all the time. When I have made a quilt, I put the pattern, samples of the fabrics, and additional design work, and a photo of the quilt into one of the sheet protectors. DON'T FORGET TO DATE IT. Also, when I enter the quilt in a show, a copy of the enty form goes in. Unfortunately, I am not always so organized and forget to put one in the book, but I am pretty good at trying to keep a "log" of the things that I have made. Don't know if it will ever get read by anyone but me, but it sure helps with the memory.
